advancedChunks?
optional advancedChunks: object;Defined in: node_modules/.pnpm/[email protected]/node_modules/rolldown/dist/shared/define-config-kYHtCO-M.d.mts:380
Allows you to do manual chunking. For deeper understanding, please refer to the in-depth documentation.
groups?
optional groups: object[];Groups to be used for advanced chunking.
includeDependenciesRecursively?
optional includeDependenciesRecursively: boolean;- Type:
boolean - Default:
true
By default, each group will also include captured modules' dependencies. This reduces the chance of generating circular chunks.
If you want to disable this behavior, it's recommended to both set
preserveEntrySignatures: false | 'allow-extension'strictExecutionOrder: true
to avoid generating invalid chunks.

}
return null
}
}will be transformed to

paths: {
'd3': 'https://cdn.jsdelivr.net/npm/d3@7'

Control which source files are included in the sourcemap ignore list. Files in the ignore list are excluded from debugger stepping and error stack traces.
false: Include all source files in the ignore listtrue: Include no source files in the ignore liststring: Files containing this string in their path will be included in the ignore listRegExp: Files matching this regular expression will be included in the ignore listfunction: Custom function(source: string, sourcemapPath: string) => booleanto determine if a source should be ignored
Performance
Using static values (boolean, string, or RegExp) is significantly more performant than functions. Calling JavaScript functions from Rust has extremely high overhead, so prefer static patterns when possible.
Examples
// ✅ Preferred: Use RegExp for better performance
sourcemapIgnoreList: /node_modules/
// ✅ Preferred: Use string pattern for better performance
sourcemapIgnoreList: 'vendor'
// ! Use sparingly: Function calls have high overhead
sourcemapIgnoreList: (source, sourcemapPath) => {
return source.includes('node_modules') || source.includes('.min.')
}default: /node_modules/
